ALLAN STEWARD CAMBRIDGE, OF KEIGrI-ILEY, ENGLAND.

GAS-PRODUCER.

To all 'whom it may concern:

Be it known that I, ALLAN STEWARD CAM- BRIDGE, a subject of the King of Great Britain, of Hereford Street Chambers, Christchurch, New Zealand, but now residing at 17 Hanover street, Keighley, in the county of York, England, have invented certain new and useful Improvements in Gas-Producers, of which the following description, together with the accompanying sheets of drawings, is a specification.

My invention relates to apparatus for use in generating or producing gas to be supplied to internal combustion engines or for heating or like purposes, and my said invention consists in so constructing said apparatus that the efhciency thereof is Agreatly increased while the cost of its production and maintenance is comparatively little.

My said invention further provides same with means for the removal of spent fuel, ashes and other refuse therefrom without permitting the ingress of air or the egress of gas into or out of same during the removal of said refuse and that without the employment of water lutes or seals for such purpose.

In carrying my invention into effect I- make use of the devices hereinafter de-` scribed and as illustrated by the accom-' dicated by the arrow a. Fig. 4f is a sectional plan on line A-B of Fig. 1. Fig. 5 is a plan showing the upper part or lid` ofmy apparatus, part of it being shown in section.

To attain the object of my invention I form the apparatus preferably of cylindrical shape, the inner chamber 2 of which is for the reception of the fuel, while the annularr chamber 3 is for the reception of water, which will act as a cooling medium for the walls of the inner chamber 2 as well as for generating steam for well known purposes. The walls 2L and 3:1L of'these chambers 2 and 3 are preferably of metal (iron) but should circumstances arise 'which render it desirable, then I may have such walls reinforced by brickwork of refractory material. The lower end of the chamber 2 opens into a receptacle 5 mounted at the Specification of Letters Patent. Ptmtd July 18, 1911, Application filed August 23, 1910.

lower part of the apparatus. This receptacle 5 is of tapering cylindrical shape and leading into it is 'a funnel shaped conductor 6, into which projects the cage-like taper guiding piece 7, mounted at the base of the fuel chamber 2. Within this barrel-shaped receptacle 5 I mount the hollow plug 8, the spindle 8a of which takes through the end wall 5L of the receptacle 5 in order that the handle 9 may be mounted thereon for the attendant to actuate same as hereinafter described.

The lower end of the hollow plug 8 is open but is contained within the cavity 5 so that the plate 10 may cover same and this plate 10 is hinged at one side and secured by the handle 10't1 at the other so that it may easily be removed. In the wall of the plug 8 a grate 11 is formed so that on being turned to its uppermost position, as shown by Figs. 1 and 3, said grate 11 is immediately beneath the fuel chamber 2, in order that the fuel may rest thereon and any ashes or particles that are too small to be supported by said grate may pass between the bars of same into the hollowplug 8 beneath. In another part of the wall of the plug 8 the opening 12 is formed so that the attendant when wishing to remove the refuse, ashes, clinkers or the like, from the base of the chamber 2, turns this opening 12 to be uppermost and so beneath the said chamber 2, consequently the loose ashes, clinkers and refuse will descend through said opening 12 into the plug 8, on which the attendantmay then actuate the plug 8 by the handle 9, in order to bring a blank part of said plug 8 opposite the opening in the walls of the barrel 5, thus preventing the ingress or egress of air or gas respectively at such time. When the plug 8 has been turned into this last named position the attendant may remove the plate 10 so that the contents of the plug 8 may be taken away, after which on replacing the plate 10, he may again actuate the handle 9 to move the grate 11 beneath the receptacle 2, thus adjusting the apparatus to enable same to continue its ordinary functions.

Mounted above the chambers 2 and 3 is a cover 13 through the upper surface of which an opening 14 is made leading from the chamber 3 to the fan 15, while through the same cover an opening 16 (in which a valve 16 is mounted) is made leading from the chamber 3 into a central dome 13a of the cover 13, which is open to the chamber 2, While fromthis space 13 another opening 1T is made to lead through the tube 18 to the up-tahe tube 19.

Fitting over the cover 13 is a lid 1 formed to be removable by being constructed and supported by any common and Well known devices at present in use for such purposes.

At a proper height from the base of tl e apparatus openings 20 are made through the Walls 3 and 2a (said openings 2O being arranged in different horizontal planes so that they may supply air to a larger body of fuel as hereinafter explained) such openings 20 being formed by bushes or sleeves extending across the chamber 3. l.llithin these bushes 22 plug valves 23 are mounted, these valves 28 being also hollow or having openings made axially through them while other openings 23 are made laterally through these plug valves so that they may be brought opposite lateral openings in the sleeves and into the openings in each of these sleeves 22 a tube 24; is inserted and fixed so that its upper end shall reach ivithin a certain distance of the cover 13.

rlfhe plug` valves 223 are actuated by handles 23 vvhile the openings taking axially through them are covered at their outer ends by plate valves which may be lirmly secured in position by the Winged nuts 25a. The lateral openings in the plug valves 3 may be turned to lead into tubes 24 for purposes hereinafter described. n'hile the plate valves 25 permit the attendant on their removal to polie the fuel by inserting a poker leading through the valves 223 to the inner chamber 2; said openings through the valve 23 also affording facilities for the attendant to inspect the fire within.

it the loiver end of the chamber 2 a pipe or passage Q6 is mounted or formed so that gases may be conducted from the apparatus to any point as may be desired7 ivhile an rip-take tube or pipe 19 is mounted to lead from the passage 26 so that during partial ignition of the fuel or when the apparatus is being firstly put into use, by openingl the valve 19ILL all air and undesirable gases may be alloived to escape until the proper gases are generated on which and on the closingof the valve 19a the gas generated by the apparatus may be Withdrawn through the passage Q6. The usual. devices as overflow or discharge pipes not shoivn are employed and mounted at the proper height in the chamber 3 so that any Water rising` within said chamber to the height of such pipe is conducted away by it.

Usual feed pipe devices for supplying Water to the chamber 3 are made use of so that the quantity being supplied may be directly under the observation of the attendant.

The Working of the apparatus is as folloivs :wOn fuel being` supplied to the proper height Within the chamber 2 and Water to the proper level in the chamber 3 and if the apparatus as shown by 1 is being employed, then by placing Water therein to the proper level as thereby shown, the fuel may be ignited at the top and by air being forced as by the fan 15 into the space in the chamber 3 above the Water therein, such air passes around said space and through the opening` 1G entering the space 15n Within the cover 18 from which it passes down to the fuel Within the chamber 2 to support its combustion. n ir thus is continued to be supplied and the resultant gases when non-- bituminous fuel is used7 descend and pass through the Whole volume of fuel beneath. lWhen bituminous fuel is used after the snpply of air has been admitted until the npper portion of said fuel has become ignited.7 then more fuel may be added through the lid 13b and at such time the valves 23 may be turned to permit air to enter the chamber Q through the tubes 2f-t and openings 2O so as to support the combustion of the fuel, in their vicinity. By these means the fuel opposite these openings 20 burns at a greater heat or higher temperature than is that of the fuel above; hence the fuel above the openings Q0 will commence to be distilled and the products of its distillatioin both gas, tarry matter and the like. Will descend through the incandescent fuel beneath in order that such of it as can be consumed is at this time consumed While the remainder continues its course in the form of a fixed gas, finally to escape through the passage 26 at the base of the apparatus to parts Where it has to be used as is Well understood. @n the valves Q3 being opened to admit air as above described should it be found that too much air is then passing through the valve 16a to the top of the fuel, this valve 1G may be partly closed While the combustion of the fuel beneath will be supported by the air passing through the tubes Q11, As will be seen during the passage of the air over the Water in the chamber 8 it Will intermix With the moisture or vapor rising from said Water and the combined air andivapor Will thus be supplied to support combustion under conditions stated above.
